3.Safety Operation Specification
Warning: To avoid such possible safety accidents as electric shock
or bodily injury, please strictly observe the following guidelines:
Prior to the use of the instrument, please carefully read the manual, and pay special
attention to the related safety warning information herein. The instrument shall be
used in stringent conformity to the instructions contained herein, or else the
protection function supplied by the instrument may be impaired or damaged.
Prior to the use of the instrument, please check the outer casing for crack or the
plastic parts for damage; check the insulating layer for damage; check whether or
not there is any exposed metal or sign of wear; and check the connectivity. If any
defect is detected, the instrument shall not be used any more.
Prior to the use of the instrument, please check the insulating layer of the flexible
clamp for damage; if any, do not use it any longer;
Prior to the use of the instrument, please measure a given voltage with the
instrument, to confirm whether or not it is in good condition;
Please use the instrument according to the measurement type and rated value of
voltage or current as indicated on the instrument or in the manual.
Please observe the local and national safety rules. Wear the personal protective
equipment (such as the rubber gloves, face masks, flame-retardant clothes etc
approved), to avoid injuries caused by electric shock or electric arc due to the
exposed dangerous live conductors.
The voltage applied between the input terminals or between any terminal and the
ground point shall not exceed the rated value as indicated on the instrument.
Measure with due caution a voltage going beyond 30V (AC true effective value),
42V (AC peak value) or 60V (DC). The voltage of this kind may cause the danger of
electric shock.
When the low battery power is indicated on the instrument, the battery shall be
promptly replaced, to avoid measuring errors.
Never use the instrument in an environment containing explosive gas or vapor
around or a wet environment.
